Process Comparison & Selection Guide

MIM / Injection Molding / CNC / 3D Printing / Mold — how to choose the best for your product?

Metal Injection Molding (MIM)

Combining powder metallurgy with plastic injection, it suits high-volume production of 3D-complex, high-density small metal parts — near-net shape, almost no post-machining.

Typical Applications

  • Consumer-electronics internal metal parts, clips, hinges.
  • Medical Surgical Instruments & Dental Components
  • Automotive Sensor Housings, Micro Gears
  • Irregular, thin-wall, internally threaded metal parts in volume.

Key Advantages / Limitations

  • Advantage: relative density 98%+, can form complex geometries hard to achieve by conventional machining.
  • Advantage: per-part cost drops markedly with volume; high consistency.
  • Limitation: constrained by feedstock and sintering shrinkage; part weight generally 0.1–100 g is suitable.
  • Limitation: Mold investment required; not economical for low volume

Precision Injection Molding

Using Haitian high-speed injection molding machines, we apply scientific molding processes covering communication, medical, and appliance housings and structural parts, with full-process CPK control from mold trial to mass production.

Typical Applications

  • Consumer electronics / appliance appearance and structural parts
  • Medical device housings, fluid reservoirs and connectors
  • Two-Shot, Overmolded, Thin-Wall High-Gloss Parts
  • High-volume, low-unit-price plastic part mass production

Key Advantages / Limitations

  • Advantage: multi-cavity per mold, fast cycle, low cost, excellent consistency.
  • Advantage: stackable silk-screen, spray painting, laser engraving, etc.
  • Limitation: mold-dependent; first mold needs time and investment.
  • Limitation: Oversized or Thick-Wall Parts Limited

Precision CNC Machining

5-axis machining centers for metal structural parts such as aluminum alloy, stainless steel, and brass, providing high precision and one-stop surface treatment.

Typical Applications

  • Low-volume, multi-variety metal prototypes and parts
  • Automotive / optical / aviation precision brackets and housings
  • Mold Electrodes, Inserts & Fixtures
  • Functional structural parts extremely sensitive to tolerance

Key Advantages / Limitations

  • Advantage: stable tolerance down to ±0.01 mm, no tooling required.
  • Advantage: flexible materials and structure; suited to rapid prototyping.
  • Limitation: high material removal; complex parts take longer.
  • Limitation: large-volume economics weaker than injection / MIM.

3D Printing (Additive Manufacturing)

For R&D verification, complex conformal structures, and small-batch customization; shortens development cycles and forms a complementary process chain with CNC and injection molding.

Typical Applications

  • New Product Structural Validation & Appearance Prototypes
  • Conformal cooling mold inserts, irregular runners
  • Low-Volume Customization & Fast Spare Parts Response
  • Topology-Optimized Lightweight Parts

Key Advantages / Limitations

  • Advantage: no tooling, extremely high geometric freedom, fast delivery.
  • Advantage: supports metals / engineering plastics, multiple materials.
  • Limitation: Surface quality and density require post-processing
  • Limitation: High-volume cost higher than traditional processes

Mold Design & Manufacturing

100% in-house development, equipped with high-precision CNC and EDM, strong in multi-cavity, two-color, and overmolding molds, with mold life above 500,000 shots.

Typical Applications

  • Injection molds (multi-cavity / two-shot / overmold)
  • MIM hardware molds and sintering shrinkage control
  • Molds for Medical & Automotive High-Appearance Requirements
  • Reverse development from customer drawings / samples

Key Advantages / Limitations

  • Advantage: in-house tooling; lead time and cost controllable.
  • Advantage: upfront Moldflow analysis; high first-trial success rate.
  • Limitation: higher upfront investment; suited to confirmed-volume products.
  • Limitation: mold is dedicated assets; low cross-product reuse.

FAQ

Real answers on mold development, quoting, and cooperation.

How long is the development cycle for a precision mold?+

Standard injection molds typically take 25–40 days, including 3D review, mold-flow analysis, CNC machining, EDM, mold trial and rework; MIM and two-shot molds range 35–55 days depending on complexity. We provide a milestone-based progress dashboard to ensure on-time delivery.

What is the minimum order quantity (MOQ)?+

Molds are priced per set; injection-molding mass production generally has an MOQ of 5,000–10,000 pieces, while the prototyping stage can provide small-batch trial production of tens to hundreds of pieces for customer validation.

How are drawings and trade secrets kept secure?+

We sign NDAs and implement tiered confidentiality management; client drawings are stored encrypted, access is granted per project, and client-specific structures are never copied or reused for third parties.

What information is needed for a quote?+

Please provide the 3D model (STP/IGS), material grade, estimated volume, and precision and appearance requirements. Based on our AI quoting tool, we can give a reference price for the mold and per-part machining within 1–2 business days.

What dimensional accuracy and mold life can be achieved?+

Mold machining precision can reach ±0.005 mm, with high dimensional stability of molded parts; mold life is generally above 500,000 shots, and key components use quality steel and surface treatment to extend service life.

What is the collaboration process?+

Requirement review → solution & quotation → contract signing → design & mold-flow analysis → machining & mold trial → sample confirmation → mass production & quality control → delivery & after-sales—the entire process is handled by a dedicated project engineer.
